Detailed Description

Built for rear service on Kia Magentis and Kia Optima models, InMotion WA512266 is a wheel bearing and hub assembly designed to replace the original rear hub with OE-style dimensions and mounting geometry. The assembly uses a 5-stud pattern with a 114.3 mm bolt circle and a modified flange profile, helping maintain correct wheel location and brake interface dimensions during repair. This part number, WA512266, is a practical choice when replacing a worn rear hub on 2006-2010 Kia Magentis or 2006-2008 Kia Optima.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Fix

• Rear wheel bearing noise or rough rotation
• Excessive hub play or looseness at the wheel
• Uneven wheel mounting caused by hub wear
• Brake rotor alignment issues related to hub dimensions
• Vibration or driveline feel from a worn rear hub assembly

Installation Notes and Tips

Confirm rear fitment by year, model, and Standard Grade application before installation. Verify flange dimensions, bolt circle, and pilot diameters against the original part, and inspect the mating surfaces, axle area, and brake components for wear or damage before assembly. WA512266 does not include an ABS sensor, so reuse or replace related sensor components as needed based on the vehicle’s existing setup.

Quality Assurance

InMotion manufactures this hub assembly using OE-based measurements and controlled production standards to support consistent fitment and durability. WA512266 is built as a direct replacement for the designated Kia Magentis and Kia Optima rear applications.
